Take a photo and saving it in full size

I'm developing an app that has to take pictures from the camera and upload them to a FireBase database. However, when I create a temporary file and try to get the image from the storage to the ImageView I get the error:

2022-05-18 11:14:18.596 24790-24790/com.example.apptonia D/Exception: /storage/emulated/0/Pictures/.temp/picture8489350187277543939.jpg: open failed: EACCES (Permission denied)

I have been trying to solve the issue adding several permissions to the manifest as suggested in other similar questions, also adding code to the Activity. However, it doesnt work.

Here's my code for the activity:
